SPARK GAP.

Application filed November 18, 1921.

T all whom it may concern Be it known that I, FRANK A. RYDER, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Spark Gaps, of which the following is a specification.

My invention relates to improvements in spark gaps, especially adapted for use in conjunction with internal combustion engines, and has for its object the provision of an improved construction of this character greatly facilitating the operation of sald engines.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter de scribed and claimed.

The invention will be best understood by reference to the accompanying. drawings forming a part of this specification, and in which,

Fig. 1 is a side view of a spark intensifier embodying the invention,

Figs. 2, 3, 4, and 5 are detail views of the different plates going to make up the body of the intensifier illustrated in Fig. 1,

Fig. 6 is a section taken on line 66 of Fig. 1,

Fig. 7 is a View similar to Fig. 6, but show ing a modified form of construction,

Fig. 8 is a view of a spark plug and in tensifier operatively connected together and each equipped with a spark gap embodying the invention,

Fig. 9 is an enlarged bottom plan view of the spark plug, and

Fig. 10 is a detail View of one of the two electrodes illustrated in Fig. 6.

The form of construction illustrated in Figs. 1. to, 6 inclusive, comprises two similar metallic electrodes 11 each provided at one end with an attaching ring 12 and at the other end with a terminal 13 turned perpendicularly thereto as shown. The electrodes 11 are arranged in a body plate 14 of the same thickness and as indicated in Fig. 6, the body plate 14 is provided with circular openings 15 to receive the rings 12 and with a central chamber 16 connected by passages with the openings 15 to receive the electrodes and their terminals as shown; By this arrangement, when the electrodes are arranged in position in the plate 14, their terminals are overlapped and arranged sub- Serial No. 516,068.

stantially parallel to each other, the end of each terminal being arranged adjacent the body of the other electrode and at the same distance therefrom as between said terminals, and whereby a substantially Z-shaped tortuous spark gap of uniform width is pro vided.

A. bottom plate 17 of insulating material provided with openings to register with the openings 15 is arranged against the underside of body plate 14 and the spacer plate 1.8 of insulating material and also provided with openings to register with the openings 15 and with a central opening 19 to register with the spark gap is arranged against the upper side of plate 14. The cover plate 20 also of insulating material, is arranged over the plate 18 and is provided with a plurality of minute openings 21 positioned over the opening 19 and through which the spark crossing the spark gap may be observed. The parts are secured together by means of metallic eyelets or tubular rivets 22 passed through the ends thereof as shown and upset to secure the parts in place. By this arrangement a simple, economical and compact construction is provided which may be attached to any ordinary spark plug of an or dinary explosive or internal combustion englue and will serve to greatly intensify and fatien the spark, thus greatly increasing the eliieiency and reliability thereof.

In Fig. 8., I have illustrated the intensifier above described as attached to a spark plug 23 and having the electrical conductor or supply wire 24 .in turn attached to the intensifier, by means of a screw bolt 25 as shown. The electrodes 26 and 26 of the spark plug 23 have their terminals 27 turned perpendicularly thereto and overlapped and positioned to form a spark gap the same as that already described and as illustrated in Fig. 9. whereby the intensifying effect of the intensifier is increased.

In the modified form of construction illustrated in Fig. 7. the electrodes 28 are embedded in a solid block 29 of insulating material. and have their terminals 13 turned perpendicularly and arranged to form the spark gap as shown, the stems of said electrodes being additionally bent as shown to increase the length of the spark gap and to render the construction symmetrical. The electrodes 28 are provided with the attaching rings 12 projecting laterally from each side of the body 29 and whereby the in-- tensifier may be readily attached to a spark plug. By this arrangement a very simple and economical construction may be provided.

While I have illustrated and described the preferred forms of construction for carryhaving their terminals turned substantiallyv perpendicularly thereto, said terminals being overlapped and arranged substantially parallel to each other, substantially as described.

2. A spark gap comprising electrodes having their terminals turned substantially perpendicularly thereto, said terminals being overlapped and arranged substantially parallel to each other, the end of each terminal being arranged adjacent the body of the other electrode, substantially as described.

3. A spark gap comprising electrodes having their terminals turned substantially perpendicularly thereto, said terminals being overlapped and arranged substantially parallel to each other, the end of each terminal being arranged adjacent the body of the other electrode and at the same distance therefrom as between said terminals, substantially as described.

4. A spark gap comprising electrodes having-their terminals turned substantially perpendicularly thereto, said terminals being overlapped and arranged substantially parallel to each other; and a casing of insulating material enclosing said terminals, substantially as described. p

5. A spark gap comprising electrodes having their terminals turned substantially perpendicularly thereto, said terminals be ing overlapped and arranged substantially parallel to each other, the end of each terminal being arranged-adjacent the body of the other electrode; and a casing of insulating material enclosing said terminals, substantially as described.

6. A spark gap comprising electrodes having their terminals turned substantially perpendicularly thereof, said terminals. being overlapped and arranged substantially parallel to each other, the end of each terminal being arranged adjacent the body of the other electrode and at the same distance therefrom as between said terminals; and a casing of insulating material enclosing said terminals, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

FRANK A, RYDER.
